DEVICE FOR REMOVING INTERNAL BOTTLE-CAPS- SPEQIFICATION forming part ofLetters Patent No. 784,851, dated March 14, 1905.

Application filed July 25, 1904. Serial No. 218,062.

To all whom itjmcty concern:

Be it known that I, FREDERICK M. GLAEs- SEL, a citizen of the UnitedStates, and a resident of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Devicesfor Removing Internal Bottle-Caps, of which the following is aspecification, reference being had to the accompanying drawings.

My invention is for a new and improved device for removinginternal capsfrom bottles, and particularly that class of caps or stoppers which arein general well known to the trade under the name of aluminium stoppersand are particularly used for stoppers for beer and malt beverages ingeneral. This well-known aluminium stopper consists of a cup-like devicein form adapted to fit within the neck of cumferential groove of such acharacter that when the cap is forced into the bottle the rubber band isheld between the groove in the bottle and the groove in the cap, therubber being pressed so that the cap is held very tightly in the bottle,so as to resist pressure'from the gas in the contained liquid. As thecap is thus constructed, this forming of the circumferential recess onits outer surface causes a corresponding circumferential ridge on theinside of the sides of the cap.

It is the object of my invention to provide a device which may bereadily, surely, and quickly operated to remove a stopper of thischaracter from a bottle, together with the rubber ring which surroundsit,without injuring the stopper, and particularly to improve upon thedevice-for removing such internalcaps shown and described in anapplication filed by me in the Patent ()ffice of the United States onthe 24th day of November, 1903, Serial No. 182,563. 1

In the accompanying drawings, Figure 1 is a longitudinal section throughmy device and part of the bottle neck and cap, showing one of the deeperforms of cap. Fig. 2 is a similar section to that shown in Fig. 1,showing, however, one of the shallower forms of cap. Fig. 3is a top orplan view of my device. Fig. 4 is a front view of my device. Fig. 5 is adetail showing the hood or guide removed from the stopper; and Fig. 6 isa detail, being an isometric view of the extractor with the hood orguide removed.

Referring to the drawings, 7 indicates a base which is provided at eachend with suitable openings through which screws may be inserted tosecure it to any suitable support, as the edge of the table 8. (Shown inFigs. 1 and 2.)

9 indicates an arm, which is preferably formed integral with the base 7and projects forward therefrom. The arm 9 has a flat portion 10, whichextends forward asuitabledistance to receive and support the guide,hereinafter described, and is provided with a screw-threaded opening 11.Forward of the flat surface 10 the upper portion of the stopper slopesdownward. The lower edge of the arm 9 is slightly curved, as shown, andis adapted to bear upon the top of the bottleneck. The forward end ofthe arm 9 is cut .from below to form a beveled or angularlyface 12.

14. indicates a second engaging edge formed upon the upper surface ofthe arm 9 a short distance above the engaging edge 13. The engagingedges 13 14 are rounded to form a curved edge, preferably formed uponthe arc of a circle to correspond with the circular shape of the insideof the cap, so as to engage the inside surface of the cap and notperforate the same, so that the cap may not be torn by the engaging ofthe edge or edges therewith and cut through the cap instead of removingthe same.

15 indicates a hood or guide, which is pressed or molded out of anysuitable material, preferably steel or similar material. The hood orguide 15 is of a general conical tion 16, extending a shortdistancetherefrom and open at the end, as is best shown in Fig. 5, and adaptedto closely lit over the arm 9 and rest firmly upon the flattened portion10 of its upper surface. The hood or guide 15 is secured to the arm 9 bya screw 17, which passes through a suitable opening in the projection 16into the screw-threaded opening 11 on the arm 9. The conical or flaringpart of the hood or guide 15 is adapted when in place, as abovedescribed, to engage the upper end of the bottle-neck and guide the arm9 into the cap in such a way that when the bottle is pressed up againstit the under surface of the arm 9 will engage the top of thebottle-neck, the beveled or angularly-disposed bearingsurface 12 willengage and rest upon the inside bottom of the cap, and the engagingedges 13 1 1, or one of them, will engage the inside upright portion ofthe cap back of the rubber band and below the top edge of the cap. Whena shallower form of cap is used, as is shown in Fig. 2, only the edge 13engages the cap, which can be readily removed, as hereinafter described,by the single engaging edge.

, l/Vhen a deeper form of cap is used, as is shown in Fig. 1, theresistance is such that a single engaging edge will sometimes leave therubber band behind when the cap is removed, and l have therefore formedthe two engaging edges 13 1 1 as above described in order that in such acase both of these engaging edges may engage the inside of the cap belowits upper edge, thus insuring its removal.

\Vhen it is desired to remove the cap from the bottle, the bottle isthrust up into the hood or guide 15, which causes the arm 9 to be guidedwith certainty into the proper position in the cap, as above described,and the bottle is pressed into it sui'liciently to insure thisengagement. The bottle is then moved down by hand into the positionshown in dotted lines in Figs. 1 and 2, thus removing the cap from thebottle.

That which 1 claim as my invention, and desire to secure by LettersPatent, is

1. In a device for removing internal bottlecaps, the combination with aflaring guide adapted to engage the top of a bottle-neck, of an armrigid with said guide and projecting within the same, adapted to bear onits under side upon the top of a bottle-neck and provided with anengaging edge adapted to engage the inside of the cap below its edge,said flaring guide and said arm being so placed with reference to eachother that when a bottle is inserted in the said guide the engaging edgeof the arm engages the inside of the cap, substantially as described.

2. In a device for removinginternal bottlecaps, the combination with apartially coneshaped guide open from below and adapted to engage the topof a bottle neck and guide the same, of an arm projecting into saidguide from one side and rigidly secured thereto, adapted to bear on itsunder side upon the top of the bottle-neck and provided at its end withan engaging edge adapted to engage the inside of the cap below the edgethereof, said guide and arm being so placed with reference to each otherthat when the neck of a bottle is thrust into said guide the engagingedge of said arm will engage the inside of the cap below the edge,substantially as described.

3. In a device for removing internal bottlecaps, the combination with anarm adapted to bear on its under side on the top of a bottleneck andhaving at its end an edge adapted to engage the inside of the cap belowits edge, ofa flaring guide secured to said arm,'par tially inclosingthe same and adapted to engage the top of a bottle-neck inserted in itand to guide said arm into engaging position in said cap, substantiallyas described.

4. A device for removing internal bottlecaps, consisting of an armadapted to bear on its under side on the top of a bottle-neck and havingat its ends an angularly-disposed or beveled bearing-surface adapted tobear upon the upper surface of the cap, the front portion of saidbeveled surface merginginto an edge adapted to engage the inside of thecap below the edge thereof, and a flaring guide secured to said arm,adapted to engage the top of a bottle-neck moved into it and to directthe arm into said cap With its engaging edge and bearing-surfaceengaging the same, substantially as described.
